GASOLINE FEED FOB INTERNAL-COMBUSTION ENGINES.

' Application filed July is,

To all whom it may concern:

Be it known that 1, CHARLES L. BASLE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Gasoline Feeds for Internal-Combustion Engines, of which the following is a specification.

This invention is a fuel feed for internal combustion engines and the like, and has for its object the provision of an improved means for automatically drawing fuel from a fuel tank into a reservoir from which it may be fed. by gravity to the carburetor of the engine.

It is a further object of the invention to provide a device of this character in which the means employed for thus' causing fuel to be fed to the carburetor includes a solid reciprocating piston arranged for sliding movement within a cylinder and actuated directly by the alternate suction and pressure created within a cylinder of the enme. g The invention will be readily understood from the following description of the accompanying drawings, in which Figure 1 is a side elevation of a fuel feed system constructed, in accordance with the invention.

Fig. 2 is a lon itudinal section through the actuating mec anism of the fuel feed system. 7

In the drawings I have shown a portion of an internal combustion engine at 1, said engine being provided with an intake manifold 2 leading from a usual carburetor 3. One 0 linder of the engine is shown at a and t e piston reciprocating within said cylinder is shown at 5. A usual fuel tank is illustrated at 6 and an intermediate reservoir. 7 is connected by a pipe 8 to the carburetor of the engine, so that fuel will be fed by gravity from said intermediate reservoir to the carburetor.

The mechanism for drawing fuel from .tank 6 into the intermediate reservoir 7 comprises a pump cylinder 9 having the reciprocating piston 10 slidable therein. One end of the pump cylinder is connected by a conduit 11 with a pipe 12 leading to the cylinder 4 of the engine. A ground joint 13 is, preferably, provided between piston 10 and the conduit 11 for closing said conduit when the piston is at the end of cylinder '9 having the conduit 11.

site end of cylinder 9 is provided with check valves 14 and 15, preferably, spring seated as by springs 16 and arranged to open inwardly toward cylinder 9 and outwardly therefrom respectively. The inwalrdly opening check valve 14 is connected to a pipe 17 leading to the fuel tank 6, and the outwardly opening check valve 15 is connected to the intermediate reservoir 7 as by screwing the nipple 18 of said valve into the top of the intermediate reservoir.

In operation the piston 10 will be recip ter the fuelwill be fed by gravity to the carburetor of the engine.

I have thus provided a construction wherein the actuating mechanism for drawing inv and discharging a supply of fuel is positively. and directly actuated by the pressure and suction within an engine cylinder, said actuating mechanism including a piston slidable back and forth within a pump cylinder in order to provide a highly eflicient pumping action.

Various changes may be made without departing from the spirit of the invention as claimed.

What is claimed is:

"1. The combination with an engine cylinder and piston of a fuel supply, a pump cylinder, a piston adapted to reciprocate therein, said piston havin a valve formed on one end thereof, a con uit leading from said engine cylinder and terminating in a valve seat at one end of said pump cylinder and adapted to receive said valve, and op.-

positely functioning check valves in the opposits end of said pump cylinder, the inwardly opening one of said check valves I communicating with said fuel supply and the outwardly opening one of said check valves communicating with a gravity feed tank.

2. The combination with an engine cylinder and piston, of a fuel supply, a pump BEST AVAILABLE COPY ciyl linder, a piston adapted. to reciprocate t erein, said piston having a valve formed on one end thereof, a conduit leading from said engine cylinder and terminating in a valve seat at one end of said pump cylinder, and adapted to receive said valves, and oppositely functioning check valves in the opposite end of said pump cylinder, the inwardly opening one of said check valves communicating with said fuel supply and the outwardly opening one of said check valves communicating with a gravity feed tank, and means for regulating said valves.

3. The combination with an engine cylinder and piston, of a fuel supply, a pump cylinder, a. piston adapted to reciprocate CHAS. L. BASLE
